Hi, I hope I’m not making a simple mistake! I can deploy the plugin fine as a widget into the sidebar, everything works as expected, but when I try to use the shortcode in a template e.g.

the box appears, all features controllable as normal, but no feeds will load. I’ve tried this in various locations on the site including the sidebar where it works OK as a widget. I also tried supplying the feed URL as parameter; again other parameters work but not feed_url. Would love to be able to get the shortcode method working!
